`||v|PRovEMENT IN PULLEYS FOR GATES.v

Specification forming part of Letters Patent No. 1lb-7.646, dated September 27, 1870.

. To a/ZZ whom i 'may concern.,-

those gates which are made to close by meansl 'of a weight, as will hereinafter be more'fully set forth and described.

Figure 1 represents a side elevation of my invention, partly in section. Fig. 2 is afront view of the same, and Fig. 3 is a plan view.

A represents the support or pivot, in which the pulley revolves; and it consists of a piece of metal, formed as shown in Fig. 1, having two or more ears formed on each side, by means of which itis secured to the post of the gate, or any other suitable support.

livotedA between the semicircular part of the support A by means of the pins or bolts B is the pulley-frame C. This frame consists of two ormore pieces of metal, of any desired ornamental shape or design, and is allowed to revolve freely in its support, so as to allowthe rope or chain supporting the weight to accommodate itself to any angle of the gate. Pivoted between the two sides of this frame is an ordinary pulley, D, over which the rope passes. This pulley, turning freely around, so as to correspond to each angle of the gate, not only prevents much wear and tear upon the rope, but always insures the gates closing.

Having thus described my invention,what I claim, and desire Vto secure by Letters Patent,

The pulley D, with its supporting frame or block G, when the same is pivoted in the semicircular frame A, so as to adaptitself to any angle of the gate, all constructed and arranged` as shown and described.
